Evaluation of nutritional risk factors in hematopoietic stem cell transplantation-eligible patients.

Objective: To evaluate the nutritional risk factors in patients eligible for hematopoietic stem cell transplantation.

Methods: A cross-sectional, descriptive study conducted with patients recruited from an hematology outpatient clinic. Study variables included demographic and clinical data, patient-generated global subjective assessment findings, anthropometric indicators, food intake and oxidative stress levels.

Correlation between nutritional assessment and oxidative stress in candidates for liver transplant.

Objective: To evaluate the oxidative profile, nutritional status and food intake (caloric value; macronutrients; vitamins A, E and C; and zinc), and to correlate oxidative stress with nutritional status in patients who were candidates for liver transplant.

Methods: This is a cross-sectional, analytical, and descriptive study with 51 candidates for liver transplant. Sociodemographic and clinical data, anthropometric parameters, food consumption, and a 10mL blood sample were collected from each patient.

Oxidative stress, inflammation, psychological status, and severity of respiratory infections are negatively affected during the pre-contest period in amateur bodybuilders.

We examined whether off-season (OffS) and pre-contest (PreC) periods affect blood oxidative stress, inflammatory, immunological, and psychological markers in 20 bodybuilders. The athletes recorded their food intake (3-day record), physical activities, mood states (Profile of Mood States, POMS), recovery-stress (Recovery-Stress Questionnaire for Athletes, RESTQ-Sport), and upper respiratory symptoms (Wisconsin Upper Respiratory Symptom Survey, WURSS-21), and blood was obtained for biochemical analysis. Almost all athletes were in positive energy balance during OffS, while bodybuilders presented markedly restricted energy intake (∼45%) leading to loss of weight (-9%) and fat mass (-45%) with preservation of fat-free mass in PreC.

Himatanthus drasticus (Apocynaceae) latex reduces oxidative stress and modulates CD4, CD8, FoxP3 and HSP-60 expressions in Sarcoma 180-bearing mice.

Ethnopharmacological Relevance: In Brazil, latex of Himatanthus drasticus is used to treat inflammation, wound healing and cancer. The present study evaluated the antitumoral potential of H. drasticus latex (HdCL) in Sarcoma 180-bearing mice (S180).

Oxidative stress and plasma lipoproteins in cancer patients.

Objective: To evaluate the relation between oxidative stress and lipid profile in patients with different types of cancer.

Methods: This was an observational cross-sectional. A total of 58 subjects were evaluated, 33 males, divided into two groups of 29 patients each: Group 1, patients with cancer of the digestive tract and accessory organs; Group 2 patients with other types of cancers, all admitted to a public hospital.
